It supports vibrant blue coloration and strong skeletal growth in SPS corals by maintaining optimal potassium levels (390–410 ppm). Lab-grade purity ensures no harmful additives, making it a cost-effective, scientifically formulated solution trusted by marine enthusiasts to keep reef ecosystems balanced and thriving. ## Description Brightwell Aquatics Potassion-P is a high-purity powdered potassium supplement designed for reef aquariums, especially ultra-low-nutrient systems where potassium depletion can occur. Potassium plays a vital role in coral skeletal structure and is incorporated into pigments that enhance vivid blue coloration in small-polyp stony (SPS) corals. In natural seawater, potassium occurs at ~399 ppm and must be maintained between 390–410 ppm in reef systems for optimal coral growth and color. Potassion-P delivers exceptional purity and concentration, with each gram offering significantly more potassium than liquid products. This makes it a cost-effective choice for hobbyists managing multiple reef tanks or high-demand coral systems. Regular use supports the development of healthy skeletal structures and helps improve pigmentation, especially when paired with adequate iron levels. This supplement is free from unwanted additives like EDTA or gluconates and contains no phosphate, silicate, or organic content. Each batch is precision-formulated based on real-world aquarium data and marine science research. For best results, test potassium levels regularly and dose consistently to maintain a stable reef environment. ## Features - SUPPORTS CORAL COLORATION & GROWTH Provides essential potassium for enhanced blue pigmentation and strong skeletal formation in SPS corals and other invertebrates. - ULTRA-CONCENTRATED & COST-EFFECTIVE Powdered format offers over 6x strength vs. liquid potassium, ideal for reef tanks with high coral demand. - PERFECT FOR ULTRA-LOW-NUTRIENT SYSTEMS Combats potassium depletion common in zeolite-based filtration, maintaining balance in ULNS reef aquariums. - FORMULATED FOR REEF AQUARIUM ACCURACY Lab-grade blend crafted by marine scientists; no phosphates, silicates, or added organics. - AMERICAN-MADE EXCELLENCE – Brightwell Aquatics is an industry-leading brand committed to providing innovative and scientifically backed aquatic care products.
